Now I know why.
Rename your folders from:
C:\Games\MILF\RJ138261\CHINGCHONG\CHONGCHING\
to:
C:\Games\MILF\RJ138261\Perverted Oneesans Happy H Apartment Life\
See my screenshot for an example.
This error ( >>3733 ) comes up when you don't have system locale set to Japanese. You have to do this because it's unfortunately not a full-blown game patch/hack, but just a simple translation patch. The translator's clearly not a programmer.
This error ( >>3742 ) comes up if your game folder is still in Japanese characters. It needs to be renamed to Latin characters because the patched Game.dat cannot handle non-Latin characters (ex. Japanese) in directory paths.
Here are my tested and working instructions for anyone else who wants to play this game:
>Game extract
• Open RJ138261.rar (with any archiver, 7-Zip is fine)
• Open RJ138261.zip (inside the rar)
• Open first folder
• Extract second folder somewhere (âQü[âÇé═é▒é┐éτé╠Game.exeé┼é╖)
• Rename that folder to Perverted Oneesans Happy H Apartment Life
>Translation patch
• Open arc_conv.exe, select Game.exe in your game folder
• Rename folder Data.wolf~ to Data
• Delete file Data.wolf
• Open Data.zip with Windows Explorer (not 7-Zip)
• Extract and replace all files in Data folder
>Play game
• Change system locale to Japanese, restart Windows
• Game should now run without errors
